[0029] like Figures 1 to 3 As shown, the utility model provides a tunnel multi-source information acquisition terminal, including a host body 1, a laser module 2, a first camera module 3, a second camera module 4 and a control module 5.

[0030] The host body 1 has a measuring panel 11, which includes a parallel panel 111, a first oblique panel 112 and a second oblique panel 113, wherein the first oblique panel 112 and the second oblique panel 113 are located on both sides of the parallel panel 111. The laser module 2 is arranged on the parallel panel 111, and is used to emit a grid laser to the inner wall of the tunnel and / or the tunnel face.

[0031] The utility model of the tunnel multi-source information acquisition terminal sets the installation angles of the first camera module 3 and the second camera module 4 so that the first camera module 3 and the second camera module 4 can respectively capture the first tunnel face image and the second tunnel face image, and finally fuse them through the control module 5 to obtain a complete three-dimensional tunnel face image. During shooting, the utility model can monitor the tunnel in real time and ensure the safety of construction personnel in real time; during monitoring, there is no need for manual multiple movements and adjustments, and the complete tunnel face image can be obtained and analyzed at one time, which effectively saves the monitoring time of the tunnel tunnel face, greatly shortens the entire construction period of the tunnel, and improves the efficiency of construction; at the same time, it also saves human resources and reduces construction costs.

[0032] Combine the following Figures 1 to 10 , the above-mentioned tunnel multi-source information collection terminal is described in detail with a specific embodiment.

[0033] refer to Figure 1 The tunnel multi-source information collection terminal of the utility model comprises a host body 1 , the host body 1 has a measuring panel 11 , and the host body 1 also has a host housing 12 connected to the measuring panel 11 .

[0034] Specifically, the measuring panel 11 includes a parallel panel 111, a first oblique panel 112, and a second oblique panel 113. The parallel panel 111 is located in the longitudinal middle of the measuring panel 11 and is parallel to the host housing 12. The first oblique panel 112 and the second oblique panel 113 are respectively located on the left and right sides of the parallel panel 111 and are inclined in a direction close to the host housing 12. The first oblique panel 112 and the second oblique panel 113 are both fixedly connected to the parallel panel 111 and the angles at the connection are both obtuse angles.

[0035] Furthermore, the upper end surface of the host body 1 is provided with a first groove 8 and a second groove 81 which are concave downward and symmetrical to each other. The shapes of the first groove 8 and the second groove 81 can be set as required. In this embodiment, the shapes of the first groove 8 and the second groove 81 are both waist-shaped. The left end surface and the right end surface of the host body 1 are respectively provided with one or more strip grooves 82. In this embodiment, the number of the strip grooves 82 on the left end surface and the right end surface of the host body 1 is four.

[0036] The host body 1 is provided with a first groove 8, a second groove 81 and a plurality of strip grooves 82, which not only reduces the overall weight of the tunnel multi-source information collection terminal, making it more convenient to carry and move, but also plays a role in heat dissipation inside the tunnel multi-source information collection terminal.

[0037] Furthermore, the tunnel multi-source information collection terminal of the present invention further includes an antenna module 83, which is arranged on the upper end surface of the host body 1. Figure 3 The control module 5 also has a wireless communication chip, which is electrically connected to the antenna module 83. The antenna module 83 and the wireless communication chip cooperate to realize wireless communication.

[0038] Furthermore, a temperature and humidity sensor 84 is also provided on one side of the antenna module 83, and the temperature and humidity sensor 84 is provided through the upper end surface of the host body 1. The temperature and humidity sensor 84 is used to detect the temperature and humidity in the tunnel. The temperature and humidity changes in the tunnel have a certain impact on the tunnel construction and workers, so it is very necessary to use the temperature and humidity sensor 84 to monitor the tunnel. The temperature and humidity sensor 84 can measure parameters such as temperature, humidity, and dew point temperature in the tunnel, providing certain guarantees for tunnel construction.

[0039] Further, such as Figure 4 As shown, a gas sensor interface 87 , a debugging interface 88 and an RJ45 network port 89 are also provided on the lower end surface of the host body 1 .

[0040] The gas sensor interface 87 is used to connect an external gas sensor. A gas sensor is a device that detects and analyzes the gas composition in a tunnel. It can monitor the concentration of oxygen and harmful gases such as carbon monoxide, carbon dioxide, nitrogen oxides, and smoke in real time. Its application enables tunnel managers to understand the gas conditions inside the tunnel more timely and accurately, strengthen the control of the tunnel environment, improve the safety level of construction, and ensure the safety of construction personnel.

[0041] The debugging interface 88 is used to debug the host body 1 to ensure that it can be used normally and make the debugged tunnel multi-source information collection terminal have more accurate monitoring. The RJ45 network port 89 is used to realize network communication through wired or wireless means.

[0042] Furthermore, a switch button 93 is provided on the lower end surface of the host body 1, and the switch button 93 is used to control the opening and closing of the tunnel multi-source information collection terminal. By controlling the opening and closing of the tunnel multi-source information collection terminal, it can be kept closed when it is not needed, reducing energy consumption, saving resources, and effectively extending the service life.

[0043] Further, combined with Figure 1 The tunnel multi-source information acquisition terminal of the utility model further includes a laser module 2, which is arranged on the parallel panel 111 and is used to emit grid laser to the inner wall of the tunnel and / or the tunnel face.

[0044] Specifically, in the present embodiment, the laser module 2 includes a laser bracket 21 and a first laser 22, a second laser 23 and a third laser 24 arranged side by side on the laser bracket 21. The laser bracket 21 is fixedly connected to the parallel panel 111. The first laser 22 is used to emit a plurality of first invisible lasers that are parallel to each other, and the second laser 23 is used to emit a plurality of second invisible lasers that are parallel to each other and perpendicular to the first invisible laser, so as to allow the first invisible laser and the second invisible laser to irradiate the inner wall of the tunnel and / or the face to form a grid laser. The third laser 24 is used to emit a visible laser, which is used for installation and debugging and demonstration to users. The visible laser can be a single laser, a plurality of mutually parallel lasers, or a grid laser.

[0045] The first laser 22 and the second laser 23 emit a first invisible laser and a second invisible laser respectively. When the two lasers are irradiated onto the inner wall of the tunnel, a grid laser is formed, which can help the tunnel multi-source information collection terminal to effectively monitor the inner wall of the tunnel and understand the deformation of the inner wall of the tunnel in real time. When the two lasers are irradiated onto the face, a grid laser is formed, which can help the tunnel multi-source information collection terminal to effectively monitor the face in real time and understand the overall condition of the face.

[0046] In some other embodiments, the laser module 2 may also be a grid laser, through which grid laser may be emitted.

[0047] Further, combined with Figure 1 , Figure 2 , the tunnel multi-source information acquisition terminal of the utility model also includes a first camera module 3 and a second camera module 4.

After shooting, the first grid laser image and the second grid laser image can be compared to determine the accuracy of the acquired grid laser image.

[0050] The first camera 32 can also capture a first palm face image, and the second camera 42 can also capture a second palm face image. Both the first palm face image and the second palm face image are color images and are two-dimensional images in different directions of the palm face.

[0051] The first fill light 33 and the second fill light 43 can provide fill light for the first camera 32 and the second camera 42 when the light in the tunnel is insufficient.

[0052] Further, such as Figure 3As shown, the tunnel multi-source information acquisition terminal of the utility model further includes a control module 5, which is electrically connected to the laser module 2, the first camera module 3 and the second camera module 4.

[0053] Specific, combined Figure 1 The control module 5 is arranged inside the host body 1. The control module 5 can control the opening and closing of the laser module 2, the first camera module 3 and the second camera module 4, so that they are in a dormant state when not in operation. The control module 5 can also fuse the two-dimensional first palm face image and the second palm face image taken by the first camera 32 and the second camera 42 to obtain a complete three-dimensional color image of the palm face and analyze the palm face information.

[0054] Further, such as Figure 1 , Figure 3 As shown, the tunnel multi-source information collection terminal of the present utility model further includes a display module 9 , and the display module 9 is electrically connected to the control module 5 .

The status marker light 92 is arranged below the plurality of display buttons 912, and the status marker light 92 is used to display the working status (i.e., the on or off status) and the communication on and off of the tunnel multi-source information acquisition terminal, and is also used to indicate the location of the tunnel multi-source information acquisition terminal, so that the tunnel multi-source information acquisition terminal can be found in the tunnel even in dim light, thereby ensuring the safety of the tunnel multi-source information acquisition terminal during the tunnel construction process. The display button 912 is used to set parameters during debugging, etc.

[0056] Further, such as Figure 1 , Figures 7 to 10 As shown, the tunnel multi-source information collection terminal of the present invention further includes a power supply module 6 , which is arranged inside the host body 1 .

[0057] Specifically, the power supply module 6 includes a battery box 61 and a battery pack 62 arranged inside the battery box 61. The battery box 61 includes a battery box cover 611 and a battery box shell 612 fixedly connected to the battery box cover 611. The battery box shell 612 is fixedly connected or detachably connected to the host shell 12.

[0058] In this embodiment, the battery box housing 612 is detachably connected to the host housing 12. When the battery pack 62 runs out of power, the power supply module 6 can be directly taken out and replaced, thereby extending the effective working time of the tunnel multi-source information acquisition terminal.

[0059] Furthermore, a bayonet 613 is provided on one side of the battery box housing 612 , and a toggle mechanism 63 is provided below the battery box housing 612 near the bayonet 613 . The toggle mechanism 63 is adapted to the bayonet 613 , and is used to fix the battery box 61 .

[0064] The toggle assembly 634 passes through the first slide groove 638 and is fixedly connected to the spring pin 632 to allow the toggle assembly 634 to drive the spring pin 632 to move left and right in the first slide groove 638. The shape of the spring pin 632 is adapted to the shape of the bayonet 613 to allow the spring pin 632 to slide to the rightmost end of the first slide groove 638 and be stuck in the bayonet 613.

[0065] When the power supply module 6 is used, the toggle plate 635 of the toggle assembly 634 can be toggled to the left to remove it for charging. The toggle shaft 636 of the toggle assembly 634 drives the fixing assembly 631 to move to the left. At this time, the spring pin 632 of the fixing assembly 631 leaves the bayonet 613, and the power supply module 6 is in an unfixed state, so it can be taken out for replacement. After the replacement is completed, the toggle plate 635 of the toggle assembly 634 is toggled to the left, and the toggle shaft 636 of the toggle assembly 634 drives the fixing assembly 631 to move to the left. The spring 633 of the fixing assembly 631 rebounds after being stressed, driving the spring pin 632 to slide to the right in the first slide groove 638 until it slides to the rightmost end. At this time, the spring pin 632 is located in the bayonet 613, and the power supply module 6 is clamped and fixed.

[0066] In this embodiment, if Figure 4As shown, a charging interface 86 is also provided on the lower end surface of the host body 1, and the charging interface 86 is used to electrically connect the active wire.
